A sterile, non-bioabsorbable, implantable device designed to be inserted into fractured bone to achieve fixation and repair; the device may also be used to attach/secure structures (e.g., ligaments/tendons) to bone, or to reduce/cease bone growth in skeletal deformities (e.g., by being implanted across epiphysial cartilage). It is typically a curved or U-shaped device made of metal alloy material, and is not adjustable after it has been applied. Disposable devices associated with implantation may be included.
